What makes the network IP cameras different than an Analog CCTV video camera?
CCTV analog cameras connect to a video monitor or DVR using a coax connection, while IP cameras connect directly to the network using a RJ45 connector and have their own IP address. CCTV or analog cameras transmit analog signals over the coax cables, while IP cameras transmit digitally encoded video over a standard network cable. IP cameras have computers and intelligence, so they can be shared by many PCs using web browser and the video recorded using video management software or a NVR.
Can I use an IP Network Camera for videoconference?
Yes, but it’s not as good as general video conferencing solutions because there is some delay in the signals through the camera and network. if the cameras use MPEG4 or H.264 compression and support audio then it can be used for two-way communications. For example you can use the Sony dome camera which has a built-in microphone and provides simultaneous transmission of both audio and video.
How do you record the video from IP cameras systems?
There are three types of recording systems: Video Management Software, Network Video Recorders (NVR), and Cloud service systems. Each one provides some unique capability.
Video Management Software (VMS) is software only that runs on your Windows computer and can be scaled to any size of system.
Network Video Recorder (NVR) is a complete system that includes the computer and software and is typically proprietary and not expandable.
Cloud service provides remote recording (over the Internet) for IP cameras at many different locations.
For more details take a look at our review and comparison of a number of these IP video recording systems.
Does IP camera need power?
The latest IP cameras get power over the network. This is referred to as Power over Ethernet (PoE). You can also add a PoE midspan or power injector between the switch and the camera. This means that you only need to run one network cable to each camera, making installation very easy.
Do you need a DVR for IP cameras?
As DVRs and NVRs handle the video data differently, they require different types of cameras. Most NVRs are used with IP cameras whereas DVRs are used with analog cameras. It's important to note that a DVR based system is a wired security system, whereas NVR systems can be a wired or wireless system.
Does IP camera work without Internet?
Even your IP CCTV cameras are without Internet access, you can still get video surveillance for your remote farm, off-grid cabin, rural home, and other areas without Internet or WiFi connection. You can get local recording even your security cameras have no Internet access.
What is an IP camera system?
An IP camera system consists of a number of network attached cameras, which are generally called IP cameras. The system also includes some type of video recording system and a number of viewing workstations. The video recording system can be either a computer running video management software (VMS, or a Network Video Recorder (NVR).
Does IP camera record?
When you record videos directly from IP cameras to the NVR, all you need to do is connect your IP cameras to your IP camera recorder via CAT 5/6 cable or wirelessly. You don't need a computer or download video surveillance software (VMS) to a computer
What is a POE IP Camera?
Power over Ethernet (POE) is a technology that lets network cables carry electrical power. For example, a digital security camera normally requires two connections to be made when it is installed: A network connection, in order to be able to communicate with video recording and display equipment.
Can IP cameras work without Internet?
Even your IP CCTV cameras are without Internet access, you can still get video surveillance for your remote farm, off-grid cabin, rural home, and other areas without Internet or WiFi connection. You can get local recording even your security cameras have no Internet access.
What's the difference between an MJPEG IP camera and a H.264 IP camera?
Not all IP cameras are created equal. When looking for an IP camera, the single biggest difference between IP cameras is the video compression format and the two most popular types are MJPEG and H.264.
In order for video footage to be transfered digitally across the internet, it needs to be compressed so that it saves bandwidth and can be transfered in a reasonable amount of time.
Video compression (or encoding) is used to transfer video footage from one place to another in a way that is more efficient than it would otherwise be. The format of this compression needs to be widely understood and utilised so that cameras and the means of transferring the video are compatible.
